AMBLTPODIA GKOTJP OP THE LTCvENID.E. 145 



Acesina paraganesa Moore, Journ. A. S. B. vol. liii. pt. 2, p. 42 (1884); de Niceville, Butt. Ind. 

 vol, iii. p. 281. n. 846 (1890). 



Hob. Northern India ; Nepal ; Sikkim ; Assam ; Java (Gecle) (Fruhstorfer). 



Expanse, d & ? , 33-35 mm. 



This species has, I believe, been hitherto confined to North-eastern India, but 

 recently Herr Fruhstorfer, of Berlin, has sent me some specimens of Arhopala to 

 determine, among which is a single male of this species taken on Gede Mountain in 

 Java ; it is not, however, a typical specimen, the underside being more like ammo- 

 nides in colour and general appearance — it is, however, most probably this species. 

 The genitalia are quite typical of the genus Arhopala, with the clasps rather larger • 

 than usual ; the penis is bent in the middle. 



Arhopala zephyretta (Doherty). 

 Acesina zephyretta Doherty, J. A. S. B. vol. lx. pt. 2, p. 33. n. 3 (1891). 



Hub. Margherita ; Upper Assam ; Cherra Punji. 



Expanse, d & $ , 30 mm. 



d & ? - Upperside : both wings dark brown ; primaries only with a very small 

 diffused patch of pale blue extending but little over the cell. Under surface with the 

 markings just like paraganesa de Niceville, but the general tone is much more uniform 

 without the strong white contrasts usually present in that species. 



This is probably only a local form of de Niceville's species. 



Arhopala ariel (Doherty). (Plate III. fig. 24, d .) 

 Acesina ariel Doherty, J. A. S. B. vol. lx. pt. 2, p. 33. n. 4 (1891). 



Hal. Margherita; Upper Assam ; Khasia Hills ; Cherra Punji. 



Expanse, d 31, ? 35 mm. 



d . Upperside : both wings very deep lustrous bluish purple ; primaries with the 

 purple colour having a strong, oval, well-defined outer margin, leaving the apex and the 

 anal angle exceedingly broadly black, the outer margin less broadly so, and the costa 

 up to the end of the cell rather narrowly black ; in the secondaries the purple has the 

 same oval outer margin, but only extends to just beyond the cell. Tail blackish, 

 tipped with white ; fringes dark, with scarcely a trace of light edging. Underside : 

 both wings dark brown tinged with purple, with a slight lilac dusting. Primaries with 

 the purple tinge confined to the costa and outer margin and the lilac dusting to the 

 apex ; all the spots are precisely as in paraganesa de N., with the exception of the 

 fourth spot of the transverse band which is shifted strongly outwards, and there is but 

 little white on the interior of this band. Secondaries with all the markings precisely 

 as in paraganesa de N., but the ground is very dark, strongly tinged all over with 

 purple, with a slight lilac dusting especially near the apex, and a prominent white spot 

 between the two outer spots on the costa.
